I have seen wind-up radios and flashlights, but I was surprised to read about a wind-up cellphone charger. From a maker of self-sufficient energy products, the FreeCharge is a collaboration with Motorola. I am hoping other cell phone manufacturers will follow suit. It may not be as convenient as plugging your phone into a socket somewhere, but it could be a lifesaver out in the wilds (or the sidewalks and malls of the urban jungle).
